The distance from lens to focal point is called?
The distance from a lens to the focal point is called the focal length.
Difference between focal point and focal length?
The focal point is the point where light converges after it passes through a concave lens. The focal length is the distance of the focal point to the lens. Same for a convex lens, except that the focal point is the imaginary point from where light deflected from lens seems to have emerged.
When curvature lens is bigger what happens to the focal point?
When the curvature of a lens is larger, the focal point moves closer to the lens. This means the lens has a shorter focal length and will converge light rays at a point closer to the lens.
What is a focal point in convex lens?
A focal point in a convex lens is the point where parallel rays of light converge after passing through the lens. It is located on the principal axis of the lens at a specific distance from the lens center, known as the focal length. This focal point is where an image is formed when an object is placed at an appropriate distance from the lens.
Where is the focal point of a cancave lens?
The focal point of a concave lens is located on the same side as the incoming light. It is a virtual focal point, meaning the light appears to diverge from this point when passing through the lens.
What is defined as the distance between a lens and its focal point?
focal length of the lens

The distance from the centre of the lens to the focal point.

How does the curvature of a concave lens affect the location of the focal point?
In a concave lens, the focal point is located on the same side as the incoming light rays. A more curved concave lens will have a shorter focal length, bringing the focal point closer to the lens surface.
Rays of light incident on lens and parallel to the principal axis of the lens converge?
This depends on the type of lens. If it is a convex lens then they converge at the focus on the other side of the lens. If it is a concave lens, then they diverge and appear to be coming from the focus present on the same side of the lens as the incident ray.
Where is the focal point in a convex lens?
If you shine a parallel (ie unfocussed) beam of light perpendicular to a convex lens it will focus to a point on the other side. That place is called the focal point of the lens. Its distance to the lens is called the focal length.
Why it is easier to find the focal point of convex lens than concave lens?
It is easier to find the focal point of a convex lens because the focal point is on the same side as the incoming light, making it more accessible to measure. In contrast, for a concave lens, the focal point is behind the lens and is virtual, making it harder to locate experimentally.
How is object positioned with respect to convex lens?
An object positioned beyond the focal point of a convex lens will produce a real and inverted image between the focal point and the lens. An object positioned at the focal point will produce no image. An object positioned between the focal point and the lens will produce a virtual and upright image beyond the lens.
